9.H.8 PumpConfiguration
9.H.9 8.5.8 PumpConfiguration
The controller in this unit energizes the appropriate
pump contacts when it receives a call for heat.
Once the call for heat is satisfied, the pumps will
remain on for the defined pump overrun time.
The Boiler, System, and DHW pump terminals are
found on the Main control board TB1-15A through
20A. They are fed 120 Volts internally from the main
power feed. The current rating of the contacts is 7.4
amps, and an appropriately sized contactor must
be supplied and installed by a qualified technician
to ensure proper pump operation. Once the system
has been installed, the “Pump Configuration” menu
will allow the installer to adjust Pump control,
Overrun time and Demand control for the various
pumps in the system.
9.H.10 StatisticsConfiguration
The statistics configuration menu allows the installer
to view Burner Cycles, Burner Run Time, DHW
Pump Cycles, Boiler Pump Cycles, and System
Pump Cycles. This menu is ‘Read-Only’

High Limit Response. That is only accessible to the
factory.
